The Project Menu

   New    : Resets the creator by deleting all items.  Warning: Make
            sure you have saved any wanted edits before selecting!

   Open   : Load a ButtonMenu datafile which you have previously saved.

   Save   : Save current edits back to the same file which you have
            just loaded.  If this a new file, a file requester will be
            available for you to enter a new name.

   Save As: Save current edits backs to another file.

   Test   : Display the menu which you have designed.  This uses the
            external BMX program to load the menu - BMX must therefore
            be in the search path somewhere.

   About  : Some copyright notes and version information.

   Quit   : Quit ButtonMenu unconditionally.
